Glasgow Embedded / Glasgow - History

arch.{arc,mips}: add explicit trailing padding fields to structures.

support.bits: rewrite Bitfield around bitarray instead of ctypes.

Update CONTRIBUTING to require uploads to Glasgow Archive.

Update repository paths after migrating to a GitHub organization.

applet: sort out required=True in add_subparsers().

In code that uses add_subparsers to choose an interact operation,
where not specifying an operation argument would not perform any
action at all (as opposed to some identification action), ideally,
required=True should be added. However, this is only available on
Python 3.7, so we can't use it just yet.
